DUDE? BODY.

Application filed June 9,

To all whom it may concern:

it known that l. Sumo Hxraenrra. a subject of Japan. residing: atDetroit. in the county of i w ayne and State of :"lichi n. have inventedcertain new and useful iniprovements in Dump Bodies, of which thefollowing is a specification.

This invention relates to dump bodies and has in view particularly adump body which will automatically rock to dumping position in the rearof the vehicle and will automatically unlock the tail gate to dischargethe contents.

Another feature of this dumping body is the tail gate construction,which permits the tail gate to be interchange-ably used as a swingingtail gate or as a platform to form an extension of the floor of the boxor hopper.

In the drawings Fig. 1 is a side elevation of the vehicle and the hoppershowing the hopper in full line in the normal position for transport.This figure also shows in dotted lines the tail gate dropped down toform a supporting platform.

2 is the-rear elevation of the hopper and the parts by which it issupported.

Fig. 3 is a plan view of the hopper-supporting parts where the hopper orbox is removed.

Fig. at is a detail view of the locking; lever and. bracket.

5 is an elevation of the tail gate hanger.

Fig. 6 shows the hopper in the dumping position.

Fig. 7 shows a modification of the locking lever.

a designates the ordinary b i; type of hopper which is supported uponrockers 7) that run onthe flanges c of the T-bar rails d.

These rockers are provided with the usual teeth e that engage inopenings in the flange of the rail to properly measure the travel of therockers on the rails and prevent their slipping; on the rails.

Located on the chassis frame and bolted to the web of the rails (Z is ayoke-like channel section cross member f having a pair of angle barclips 9 to which are riveted the angle section rack bars 2'. Bolted tothe plates are. the locking lever bearings 70. m designates a yoke onthe end of which is bolted the bell crank member a see Fig.

1922. Serial NO. 567,012.

one arm of which is screw-tlu'eaded as at o to take the adjusting andlock nuts 7'). This arm adapted to pass through the slot .7 in keeper orbracket 7. the nuts hooking in under the wall that bears the slot lockthe hopper in position for transport. i no purpose or making this bellcrank lock ing lever threz'idedis to permit the two nuts to be adjustedto make each lever catch in under the shoulder on the keeper so that thehopper will be locked at each side and hence will not vibrate at oneside due to a looseness at this point.

Fastened to the center of the cross member 7' is a checking linecon'rprising' the extensible spring unit 5 and the chain If which isprovided with a ring adapted to pass through the slot u in the plateAfter the ring; has been passed through this slot, the chains may bedropped down into the reduced end of the slot so as to lock the same inthe plate at any desired point along the chain.

The OPQI'E'itlOH of this part of the dumping apparatus will be apparent.By lifting; the yoke 71?, the locking lever 0 has its end lifted outfrom under the shoulder of the keeper r and the hopper is free to rollto dumping position. The calculation of the center of the rockers withrespect to the center of gravity of the hopper when loaded is such thatthis center of the load lies behind the center of the rocker andconsequently the load will. anton'xatically carry the hopper to dumpingposition when the locking yoke is lifted to release the locking lever.The notches shown in the inclined supporting bar 2' permit the lockingbar m to rest in various positions and consequently hold the hopper invarious positions of inclination. depending upon the amount of checkingchain used. The amount of chain used may be varied by locking); the sameat any desired point along the chain and in the slot or.

The main feature I have in mind is the automatic releasing of the tailgate following): upon the rolling of the hopper to dumping position: Thetail gate is normally held in locked position by the pivoted hook orlatch to engaging behind the keeper m on the tail gate. During transportthe hook on is maintained in locked position with the keeper m by theweight of the locking lever y. This locking lever is threaded on to thecrank shaft 2 through an eye in the locking lever. Normally a hanger Zsecured to the bottom. of the hopper prevents the locking lever droppingdown from the position bored and tapped rod portion and a threaded stemportion which screw together and form are provided with a jam nut 3 sothat the length of the connecting rod may be adjusted to meetrequirements.

Still another feature is. the inter-changeable arrangement ofthe tailgate so that it can act as'a tail gate swinging on a hanger located atthe top of the gate or it may be optionally used as a carrying platformor extension of the hopper floor as is shown in the .dotted lines ofFig. 1. The gate isprovided with studs 1 which set into the rests 5 onthe inside of the castings 6 which might appropriately be termed thetail gate hangers. These hangers are bolted to the top rear corner ofthe hopper. These rests 5 open-top-pivotbearings. The tail gate may haveits pivot studs lifted out of the open-top-pivot-bearings and the hooks6 may then be engaged in the slots 7 of the rear bent-end-angle-bar ofthe hopper designated 8. This bar is a U shaped anglebar that runs upthe sides as well as running across the back of the hopper to give itits box-like shape and reenforcement atthe corners. lVith the hooks 6hooked into the slots of this bar the chain 9 may support the rear ofthe tail gate from the slot 10 in the tail gate carrying bracket 6.

This chain can be run through the perfo rations 11 in the keeeprs whennot in use and the two hooks 12 may be hooked to gether and supported atthe back of the tail gate. When in actual use the chain hooks 12 arehooked into the slots 13 at the free end of the tail gate; These slotsare in the castings 14F. which also form gusset plates for the cornersof the tail gate. The other end of the chain isanchored lll'tllfireduced end of the slot 10 carried in the casting 6. The chain, when inthe position shown in Fig. 6 acts as a check chain to limit the openingof the tail gate.

InFig. 7 I have shown a modification of the locking. lever in which aspherical headed bolt 101 with two lookingnuts 10:2 and 103 are used totake up any looseness between the locking lever and the keeper.

What I claim is: 1. The combination of 'a. vehicle, a rear dumpinghopper supported upon the vehicle and provided with a plate having aslot with .a' reduced end, an'inclined supporting bar provided withnotches. a bracing member secured to the hopper and arranged to engagein the notches to support the hopperin different degrees of inclination,and a checking chain secured to the, vehicle and arranged to engage inthe said slot with the reduced end at various points alongits length.

2. The combination of a vehicle, a rear dumping hopper supported uponthe vehicle, an inclined supporting member provided V with severalplaces for supporting the-hopper in several positions of inclination indumping, a bracing member secured'to the hopper forreeting o'n'any oneof the several places of said supporting membe1g=and a checking chainanclioi'ed ipoiithe vehicle and which may be engaged with the hopper tovary its effective checkinglength.

'3. The combination of a vehicleya 'rear dumping rolling hoppersupported upon rockers, a keeper secured to the vehicle and providedwith a slot,'a locking lever secured to the hopper and provided with abell crank member, one arm having a clamping member adjustable thereon,the said arm adapted to fit in the slot of the keeper member and theclamping member adapted to bind, the looking lever in looking relationwith "the keeper member. g V v V j 4t. The combination of a vehicle, arear dumping rolling hopper supported upon rockers, a keeper secured tothe vehicle and provided with a slot and a locking lever having an armsecured to the end thereof and secured'to the hopper, said armengagthereon and engaging in said slot, said.

clamping member arranged to engage under the keeper.

Intestimony whereof I affix my sign ture.. V
